To all whom fitlmag/ concern:

- Be it. known `that I, CHARLEs'CUNb, a

citizenv ofthe United States', residing at Connecticut, have invented certain 4new and Meriden, cdunty o f New Haven, State of useful Improvementsin Terminal-Connector Construction, of which the following is a full, clear, and exact'description.'

My invention relates tol a new and iml proved terminalconnector, the invention retion', whereby thejvarious part-sof th'e connector may be -s'ecuredtogether very strongly,

v and wherebyin. use, when the'connector is slipped on and off, all danger of breaking the electrical connection. of the connector and the wire carried thereby' is avoided.

0 In the drawings, Figure 1 is aside eleva tion of my improved connector applied to' a spark plugs, secalled, said connector' being shown in posltion for use.' Fig. 2 is :25. a View of the connector detached from its' companon part. Flg'. 3, is a relatively j en v #larged sec'tlonal View shbyvmgthe construe-- tion. l

- the eXtreme' edge ofthe sleeve maybe upset 'or expanded as shown to hold the bridge 4f and spring arms 4--1 rigidly to thesleeve 3.

.Obviously, this method of connection is merely preferential and maybe modified in a variety of ways. s

The presence `of the inner end of the screw in the insulated wire 1 tends to expand or wedge the surrounding insulation causing it to hug the inner wall of the han-- dle 2, thus augmenting the holding action of said screw. by the frictlonal en agement thus of the wire or MERI'DEN, coismECTIcU'r..
